Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 772, here are decompositions:

  • 3 + 769 = 772
  • 11 + 761 = 772
  • 29 + 743 = 772
  • 53 + 719 = 772
  • 71 + 701 = 772
  • 89 + 683 = 772
  • 113 + 659 = 772
  • 131 + 641 = 772

Showing the first eight; more decompositions exist.
